Capacitor electronics ka esa componet he jisko DC power supply dene par Vah charge ho jata hai(capacitor ki ek plate par positive charge or doosri plate par Negative charge aa jata hai). Or uska charge Long time tak bna rhta hai. Capacitor ki isi properties ke karn vah battery ki tarha work karta hai.
Needs of components (आवश्यक सामग्री)
- Battery 🔋( 9 volt )
- Switch
- Electrolyte Capacitor (1000 uF, 25 volt)
- Resistor (470 ohm)
- An LED
- Connecting Wires.
Niche diye gaye circuit ke aadhar par components ko connect kiya jata hai.
(a) Circuit Diagram |
Working -
Jab hm switch off kr dete he to battery se connection open ho jata hai or battery se ab koi current flow nhi hoti hai.
Yha capacitor ke karan LED OFF nhi hoti hai, kuki capacitor charge hua tha or ab vh LED ko power deta hai. LED tab tk ON rhti hai jab tak ki capacitor discharge nhi ho jata.
Jab ham switch ON krge to capacitor phir se charge ho jata hai.
Capacitor as a battery |
Connection krte time dhayan de ki capacitor or LED right Polarity par connect ho i.e. Capacitor ka positive terminal battery ke positive terminal se or Cap. ka negative terminal battery ke negative terminal se connect ho. Same LED ko bhi right Polarity par lgaye.
Direct connect to the LED with Charged Capacitor -
LED ON using Capacitor |
Note - Connection karte time dhayan dena chiyye ki Capacitor ki legs ko apne nagn hatho se touch na ho, Capacitor ke terminals hmari body ke sath touch hone par capacitor hmari body me discharge ho jayega. Jisse hame bhut tej shock ( current) lgega. Capacitor ke kisi singal terminal se to current nhi lgega. Agar dono terminal body se touch hote he to shock ka lgna avsay hai.
Ye shock itna tej ho skta hai ki kisi ki death bhi ho skti hai.
Power supply na hone par charger ki LED ku glow karti hai ?
Ye question har kisi ke mind par jaroor ata hoga ki jab electronics device ON rhti hai to device me Indicator LED ON rhti he. Par jab Power supply band kar di jati hai to LED kafi long time tak ku glow kati hai -???????
Esa isliye hota hai kuki LED ke parallel me 1 capacitor connect rhta hai jo power supply ke hone par charge hota hai. Or power Supply ke na hone par LED ko back-up deta hai. Or LED Glow karti rahti hai.
Electricity ke fluctuation (ON - OFF) hone par System ke damage hone ka khatra rhta hai, Jis karn Circuits me Capacitor ka use kiya jata hai.
